error -10810 . the application Finder could not be opened
Hello
I recently (about 2 days ago) updated my early 2008 Mac Pro through the standard software update and since doing so my computer has begun acting like it wants to crawl into a hole and die.
There are a number of issues I have noticed. After using the computer for maybe 10-15 minutes I am no longer able to select any applications from my dock and when trying to access the finder it becomes unresponsive. I can then no longer open any programs and if I am lucky I might be able to close whatever curnent program I am using. Sometimes when I try to open a finder window I get the error message -10810 'The application Finder could not be opened'
for a while I could not empty my trash as well although that now seems to have passed.
image icons for some programs in my dock have vanished but when i hover over the space where the iconused to be the program seems to still be there.
I have no idea when my comptuer might freeze. sometimes it's within 10 minutes and other times it is within 1 minute of starting. It's so bad that since updating my mac 2 days ago I have not been able to shutdown the computer properly and have to hold the power button to turn off.
I have tried doing a disk utility verify and it does not seem to find anything wrong with my hard drive.
can anyone help. It's a pain lugging this thing to my nearest Mac store as I don't have a car.
I am using OSX 10.6.8
thanks
